Gumshoe

Gumshoe is part of the small little detective skins they have put together late in Season 4. A "gumshoe" is a detective or private investigator, it's a term that originated in the late 1800s. The Gumshoe skin is more unique than Noir and Sleuth which are pretty much just re-colorings of each other. It features pretty standard detective apparel, but with purple highlights on the hat and tie.
